On Friday, self-professed members of Anonymous and their friends joined together in a unique new holiday: a concentrated effort to make fun of the terrorist group Islamic State.

Referred to as #trollingday on Twitter, the event was meant to both take the wind out of actual online ISIS supporters’ sails and provide an opportunity to mock a group that in the past month has engineered or inspired deadly attacks in Paris, Beirut, and California.

In theory, Trolling Day is meant to specifically zero in on ISIS militants, though in practice, a number of them encourage viewers to mock Islam specifically—which is ironic and potentially counterproductive, considering ISIS has very clearly stated their desire to eliminate the “grayzone,” its term for the peaceful coexistence of moderate Muslims and the West.

The “trolls” largely took the form of Photoshopped images and have a handful of recurring themes. ISIS members having sex with goats or thwarting the Islamic instruction to not eat pork play prominent roles. Continuing the grand tradition of the prankster who confused reporters with a mock ISIS flag made out of sex toys, a number of the images deride ISIS’s attempt to criminalize homosexuality by Photoshopping fighters supporting gay rights or engaging in gay sex acts. And, for reasons not fully apparent except for the pun “Allahu Quackbar,” some Anons change ISIS figures into rubber ducks.

Here’s a small sampling of their accomplishments. Again, these are NSFW.
